That's odd. The first question that pops to mind: Do you use the

What is also odd is that I can open the file with no problem using a
text editor on the Mac, indeed the file preview in the Mac file
Manager (Pathfinder) reads it without any problems. BUT I have just
tried on Ubuntu (open with text editor) , and it won't open.
I certainly haven't selected the compressed option, but this
particular file is 7 months old, and I can't remember whether it
originated on the Mac or Ubuntu or even the version of Lyx. I will
check the compressed option in future.
However, it seems there is no obvious answer, so I will just be more
cautious in future.
This file is definitley corrupt. Here's the result of "hexdump -c | head
-n 25":

As you see, the file begins with some huge number of zeros, and then
starts up again in the middle of a LyX file, with "\end_layout", as
Liviu noted. Most of the file has thus been zero'd out.
If you've had this problem more than once, you may want to think about
whether you have a hardware problem that is corrupting your files.
